near record highs on Friday, before a possible wet weekend...

watching the tropics for early to middle of next week...

discussion...

high pressure over the western atlantic waters will continue to
remain nearly stationary through this weekend, as an upper level
low over the bahamas moves westward into the gulf of mexico.

This will allow for a tropical wave near hispaniola to move west
northwest and through south florida this weekend.

The atmosphere will be drier over south florida on Friday ahead
of the tropical wave leading to less coverage of showers and
thunderstorms, and the focus will be over the interior and west
coast metro areas. The showers and thunderstorms will then
increase again to scattered to numerous over south florida this
weekend with the passage of the tropical wave.

Highs on Friday will be near record ranging from the mid to upper
90s over south florida, due to the lower shower and thunderstorm
coverage. The heat indices across south florida on Friday will
also be in the 105 to 107 range.

extended forecast...

the weather for south florida for early to middle of next week
will depend on tropical disturbance currently located about 1200
miles east of the leeward islands. At this time, the models are
showing this tropical wave to move to the west northwest around 20
mph through the weekend and should be in the south florida region
sometime between Tuesday and Wednesday of next week. NHC is giving
this tropical disturbance a 60 percent chance of development into
a tropical system through the weekend. All residence and visitors
or south florida need to continue to monitor this tropical
disturbance through the weekend.

Marine...

the winds will be from the southeast direction tonight through
this weekend with speeds of 15 mph or less over most of south
florida waters. The only exception to this is over the atlantic
waters where the speeds could increase to 15 to 20 knots on
Saturday. The seas will remain at or below 4 feet in the atlantic
waters and 3 feet or less in the gulf waters this weekend.

The threat of rip current could increase this weekend along the
east coast beaches of south florida, due to the increase in
easterly wind flow.

Fire weather...

the relative humidity over south florida will remain well above
the critical value this weekend, as the dispersion index values
will be in the fair to good range. Therefore, there should be no
issues with the fire weather over south florida this weekend.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
